SDL2 linking errors on macOS

SDL Development
1

Hi. I’m developing a cross-platform app using CMake and vcpkg. SDL2 is compiled by vcpkg and then is added to the project like this:

find_package(SDL2 REQUIRED) # provided by vcpkg
target_include_directories(${TARGET} PRIVATE ${SDL2_INCLUDE_DIRS})
target_link_libraries(${TARGET} PRIVATE ${SDL2_LIBRARIES})

This works fine both on Windows (dynamic library) and Linux (static library), however on macOS (static library) I get the following errors during linking:

Undefined symbols for architecture x86_64:

I use the precompiled SDL2 Framework for MacOS without any problems. Is there a specific reason you’re compiling it from source?

Looks like you need to link to CoreAudio.

Is there a specific reason you’re compiling it from source?

I prefer my apps to be self-contained and to not rely on system-wide installed libraries. And installing libraries globally often causes versioning issues if multiple projects rely on different versions of the same library.

Anyway I’ve tried your approach, but now I have compilation errors because ImGui includes SDL like <SDL.h> and not like <SDL2/SDL.h> which Apple frameworks mandate. And I’m using ImGui as a submodule, so modifying its sources is not something I’d really like to do, especially when it works on all other platforms.

Looking at the symbols I see that CoreAudio is definitely not the only library needed. In fact, it seems that all the platform dependent libraries which SDL needs on macOS are missing. But I don’t get how I would link them, because, for example, doing -lCoreAudio is not enough and only yields an error.

Anyway, to further test this I’ve temporarily modified all the inclusions of SDL in my project, and the framework approach does indeed work correctly. So it seems the issue might be in the way vcpkg compiles SDL on macOS. I’ve created an issue on their GitHub.

Of course, but I simply embed the SDL (and SDL_ttf, SDL_net) frameworks in my app, it’s no less “self-contained” than had I built them from source.

I do have to use install_name_tool to change the path to the frameworks from the system-wide location to the local copy in the app:

install_name_tool -change @rpath/SDL2.framework/Versions/A/SDL2 "@executable_path/../Frameworks/SDL2.framework/Versions/A/SDL2" BBCBasic.app/Contents/Resources/bbcsdl
install_name_tool -change @rpath/SDL2_ttf.framework/Versions/A/SDL2_ttf "@executable_path/../Frameworks/SDL2_ttf.framework/Versions/A/SDL2_ttf" BBCBasic.app/Contents/Resources/bbcsdl
install_name_tool -change @rpath/SDL2_net.framework/Versions/A/SDL2_net "@executable_path/../Frameworks/SDL2_net.framework/Versions/A/SDL2_net" BBCBasic.app/Contents/Resources/bbcsdl
